Women who have high alcohol intake, 14 or more servings of alcohol a week are slightly more likely to have reduced fertility, suggests a study published in The BMJ today.
In developed countries, up to 24% of couples experience infertility, defined as time to pregnancy of 12 months or more. Official guidelines in countries like the USA, UK and Denmark recommend that women trying to become pregnant should abstain from alcohol consumption. But the extent to which alcohol intake affects female fertility is unclear. So a group of Danish researchers carried out a large prospective cohort study to examine the association between pre-conception alcohol consumption and time to pregnancy.
